Some Basic Concepts of Chemistry
Description: Matter refers to anything that occupies space and has mass, measured in SI units such as kilograms (mass) and cubic meters (volume).
Description: Physical properties describe characteristics of matter (e.g., color, density). Scientific notation, significant figures, and chemical laws govern accurate measurement and reactions, ensuring mass conservation.
Description: These foundational principles state that elements combine in fixed ratios (Law of Definite Proportions), multiple ratios (Law of Multiple Proportions), and gases react in simple volume ratios (Gay-Lussac's Law). Dalton's Atomic Theory posits indivisible a
Description: The mole concept quantifies substances, molecular mass sums up constituent atoms, formula mass calculates compounds, molar mass measures a mole's mass, and Avogadro's Law relates volume to quantity.
Description: Avogadro's number (6.022 x 10^23) represents the number of particles in one mole. Equivalent weight quantifies the mass of a substance reacting with one mole of electrons.
Description: Percent mass of an element calculates its proportion in a compound. Empirical formula shows simplest ratio of atoms. Molecular formula gives actual ratio. Numericals apply these concepts quantitatively.
